jsp页面乱码_Java Web开发

jsp页面乱码

jsp页面单独运行不乱码,从servlet传值就出现乱码!!下面是jsp和servlet的代码!!
<%request.setCharacterEncoding("GBK");%>
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title><%
request.setCharacterEncoding("UTF-8");
if(request.getAttribute("smsg")!=null)
{
String smsg=request.getAttribute("smsg").toString();
out.print(smsg);
}
else
out.print("成功页");

%></title>

</body>
</html>
================================================================
request.setCharacterEncoding("GBK");
request.setAttribute("smsg", "注册成功");
request.setAttribute("suc", "注册成功!");
request.setAttribute("sback", "userlogin.jsp");
this.getServletContext().getRequestDispatcher("/Success.jsp").forward(request, response);

大家给我看看帮帮忙!!!

你这个传值是从Servlet传到JSP是吧``
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%> 你这个JSP页面是GBK
<%request.setCharacterEncoding("GBK");%> 你在最上面是用的这个编码，这是对的
但是
<title><%
request.setCharacterEncoding("UTF-8");
if(request.getAttribute("smsg")!=null)
{
String smsg=request.getAttribute("smsg").toString();
out.print(smsg);
} 你在下面又用 UTF-8编码显示的时候肯定是乱码把这个去掉或者改成GBK

----------------解决方案--------------------------------------------------------

我把第一句的和request.setCharacterEncoding("UTF-8");
都删除掉了,还是乱码!!
改成request.setCharacterEncoding("GBK");
之后也还是乱码.
这是为什么呢!!
我用response.sendRedirect();跳转就不会乱码,但是值带不过去!!

----------------解决方案--------------------------------------------------------
......
一般只要request.setCharacterEncoding("GBK");这个就不会是乱码了``
那你把request.setCharacterEncoding("GBK"); 和 request.setCharacterEncoding("UTF-8");都删除了
然后 String smsg= (String)request.getAttribute("smsg").toString();
String smsg1 = new String(smsg.getBytes("ISO-8859-1"),"gbk");
out.print(smsg1);

你在试一下看``要是还是乱码我就不清楚了``

----------------解决方案--------------------------------------------------------

还是不行,我真是服这个页面了!!
是jsp页面的问题还是servlet的问题,我别的页面都没有什么问题,只有这个页!!
